Well, the number is decimal form, is in the thousandths place, so the denominator, would be 1000's:
0.275 = 275⁄1000 
Then, you have to Simplify 275⁄1000 In which, you would get:  11⁄40

Move the decimal over three places to make a whole number. Then put over 1000(matching number of zeros to number of places moved. Then simplify.
You should be able to simplify 275/1000 to 11/40 by dividing each by 25

Answer:

small number is 14

Larger number is 31

Step-by-step explanation:

Let x = one number

Let y = the second number

x + y = 45

x = y - 17

Put y - 17 into the top equation for x

y - 17 + y = 45

2y - 17 = 45 Add 17 to both sides

2y = 45 + 17

2y = 62 Divide by 2

y = 62/2

y = 31

How to find the surface area of a trapizoid formula, maybe walkthrough if possible?

TEA [102]

Trust me, it's really easy!
break apart the shape (In 3D, I assume.) there should be 6 breaks apart. The top, bottom, and four sides. After you find the area, (Base x Base x Height for the 4 sides, and Side x Side for the top and the bottom of the figure.) Then you add all of them up, and there's the surface area! If you need more help, message me, I'd be glad to help.

Sam makes bread rolls he gets 2/5 of the bread rolls to his neighbor and 4/9 the remainder to his cousin he has 15 bread left ho

Kitty [74]

Answer:

Sam made 45 rolls

Step-by-step explanation:

After giving some to his neighbor, Sam has 1 -2/5 = 3/5 of the original quantity left. After giving some to his cousin, he has (3/5)(1 -4/9) = (3/5)(5/9) of the original quantity left.

(3/5)(5/9) = 3/9 = 1/3

15 rolls = (1/3)·(original number) . . . . . . Sam has 15 roll left

45 rolls = original number . . . . . . . . . . . multiply by 3

_____

Check

Same gave 2/5·45 = 18 rolls to his neigbor, so had 27 left. Sam gave 4/9·27 = 12 to his cousin, so had 15 left.

The levels of mercury in two different bodies of water are rising. In one body of water the initial measure of mercury is 0.05 p

NNADVOKAT [17]

Answer:

0.05 + 0.1y = 0.12 + 0.06y

Step-by-step explanation:

Here, we want to find y which is the heat in which the amount of mercury in each of the water bodies is same.

Now for the first water body:

Initial is 0.05 ppb and after y years, we have a rise of 0.1 * y = 0.1y ppb

So the amount of mercury in ppb after y years would be; 0.05 + 0.1y

For the second water body;

Initial is 0.12 and a rise of 0.06 ppb per year for y years. The rise would be 0.06 * y = 0.06y

So total amount of mercury here is 0.12 + 0.06y

So to find y which is the year the amount of mercury in each water body is same, we simple equate both and that would be;

0.05 + 0.1y = 0.12 + 0.06y

T=p(0.09)2/3, where p is the original amount in the account, if the original account amount was $2570, what is her current balan

DanielleElmas [232]

The current balance amount is $154.20

Step-by-step explanation:

Given,

$T = p(0.09)\frac{2}{3}$

Where;

p represents the original amount in the account.

Given original amount in the account = $2570

Putting p=2570

$T=2570(0.09)\frac{2}{3}\\\\T=\frac{462.6}{3}\\\\T=154.2$

The current balance amount is $154.20
